Difficult: Keira has hinted that her relationship with Rupert may be on the rocks

The Hollywood star, who is set to star in the West End as Jennifer in a production of The Misanthrope, was asked if she could relate to her latest character.

She said to The Times: "Do I recognise being an extremely well-known young actress? Yes. And she's in the middle of a world full of people who are quite a bit older than her. She's having a problem with her boyfriend. No comment."
